LOSPOR — Large Open Source Perioperative Register

LOSPOR is a free, open-source web application for anaesthesiologists to record perioperative data and generate standardised anaesthesia protocols. It is designed for clinical use in Bulgaria and is available in both English and Bulgarian.

What does it do?​

LOSPOR guides the anaesthesiologist through three forms for each case:

  1. Preoperative assessment — patient demographics, diagnosis, airway evaluation, risk scores, vitals, and labs
  2. Intraoperative record — real-time timetable of vital signs, drugs, agents, infusions, and fluids
  3. Postoperative recovery — Aldrete score, pain, disposition, and handover instructions

At the end, LOSPOR automatically generates a printable two-page anaesthesia protocol (PDF) containing all entered data in a standardised, professionally laid out document.

Who is it for?​

  • Anaesthesiologists recording cases and generating protocols
  • Anaesthesia nurses contributing to case records
  • Heads of department overseeing institutional cases and assigning staff
  • Researchers accessing the anonymised perioperative dataset

How does it work?​

Clinician registers → Opens new case → Fills preop form
  → Fills intraop form (live timetable) → Fills postop form
  → Protocol generated → PDF printed → Anonymised data stored

Patient-identifiable information (name, ID number) is entered only at print time and is never uploaded or stored in the database.

The live application is available at app.lospor.org.
